| ## - __LINKEDIT segment filesize may change (4 lines) |
| ## - LC_CODE_SIGNATURE command dataoff and datasize may change (3 lines) |
| ## - __LINKEDIT data locations may change |
| ## NOTE: The {N;N;N;N;d} means delete the next four lines for BSD and GNU sed. |
| ## The ,+4d is a GNU extension which seems not to work in macOS 10.15 |
